Here, we find that many Genomic islands have origins of transfer (oriT) mobilisable by conjugation, incl. known Pathogenicity & defense islands. iOriT use only an oriT for transfer by hitching on conjugative elements: they make abundant, diverse, ancient families of mobile genetic elements. See🧵

Bacteria swap DNA far more than we thought. This study shows recombination between species can blur genetic boundaries, with up to 95% of diversity coming from hybrid DNA in some microbes.

Happy that our work on the evolution of Yellowstone cyanobacteria is now published in @elife.bsky.social: doi.org/10.7554/eLif...! Did a lot of work in revision—many thanks to the anonymous reviewers for great suggestions! Also see the eLife digest for a summary: elifesciences.org/digests/9084...

New preprint to close out the year! Led by Alana Papula and together with Daniel Fisher, we used single-cell genomes to infer the evolution of Prochlorococcus—one of the most abundant and genetically diverse bacteria on Earth. Check it out here: doi.org/10.64898/202...
